Abstract

Ein Mehrkomponenten - Photometer enthält eine ein Kontinuum emittierende Lichtquelle (10), von welcher ein Meßlichtbündel (12) ausgeht. Das Meßlichtbündel (12) tritt durch eine Probenküvette (14) hindurch, in welche ein Probengas einleitbar ist. Eine Mehrzahl von ersten Gasküvetten (26), die mit unterschiedlichen, in dem Probengas gesuchten Gasen gefüllt sind, und eine oder mehrere zweite Gasküvetten (28), von denen jede wenigstens einer der ersten Gasküvetten (26) zugeordnet ist und welche ein Referenzgas enthalten, sitzen in einem ersten Filterrad (22) und sind wahlweise in den Strahlengang des Meßlichbündels (12) bewegbar. Ein oder mehrere Filter (32), von denen jedes nur einen begrenzten Spektralbereich um eine Absorptionsbande eines in einer ersten Gasküvette (26) enthaltenen Gases herum durchläßt (Blockingfilter), sitzt in einem zweiten Filterrad (24), durch welche wahlweise eines der Filter (32) in den Strahlengang des Meßlichtbündels bewegbar ist. Ein Detektor (36) ist von dem Meßlichtbündel (12) beaufschlagt. Die Filterräder (22,24) sind so gesteuert, daß ein und dasselbe Blockingfilter (32) in Verbindung mit dem zugehörigen ersten Gasfilter (26) und in Verbindung mit dem zu diesem ersten Gasfilter (26) gehörigen zweiten Gasfilter (28) im Strahlengang des Meßlichtbündels (12) angeordnet ist. A multi-component photometer contains one Continuum-emitting light source (10), one of which Measuring light beam (12) goes out. The measuring light beam (12) passes through a sample cell (14) into which a sample gas can be introduced. A plurality of first Gas cuvettes (26) with different in which Sample gas searched gases are filled, and one or several second gas cuvettes (28), each of which assigned to at least one of the first gas cuvettes (26) and which contain a reference gas, sit in one first filter wheel (22) and are optionally in the Beam path of the measuring light beam (12) can be moved. One or several filters (32), each only a limited one Spectral range around an absorption band one in one first gas cuvette (26) contained gas passes around (Blocking filter), sits in a second filter wheel (24), through which one of the filters (32) can optionally be Beam path of the measuring light beam is movable. A Detector (36) is from the measuring light beam (12) acted upon. The filter wheels (22, 24) are controlled that one and the same blocking filter (32) in connection with the associated first gas filter (26) and in connection with the second one belonging to this first gas filter (26) Gas filter (28) in the beam path of the measuring light beam (12) is arranged.
